4 Claims.

The present invention relates to a valve mechanism for water closets.

An object of the invention is to provide manually operable means for opening a valve in the lower portion of a water tank so that the water may be discharged into the drain pipe supplying the water closet wherein the manually operable means is positioned below the valve and the valve member provides a bonnet for preventing water from escaping from the manually operable means.

Another object of the invention is to provide a floatable valve member for closing the drain pipe having means associated therewith forlimiting the movement of the floatable valve member away from the seating position.

Other and further features and objects of the invention will be more apparent to those skilled in the art upon a consideration of the accompanying drawing and the following description wherein an exemplary embodiment of the invention is disclosed.

In the drawing:

Fig. 1 is a sectional view of the tank showing the position of the valve operating mechanism when the floatable valve member is in closed position.

Fig. 2 is a similar sectional view illustrating the position of the manually operable means when the valve member is in an open position.

Referring to the drawing there is shown at a a tank adapted to receive a supply of liquid for use in connection with a. water closet. The liquid is admitted to the tank a through a valve shown diagrammatically at l and the valve is controlled by means of a float 2 in a well-known manner.

The lower part of the tank is provided with a drain pipe 3 and the upper end of the drain pipe is provided with a bushing 4 having a conical shaped surface for receiving the floatable valve member I). The valve member b is formed of rubber or elastic material having a depending skirt so as to be hollow and therefore buoyant. The fioatable valve member carries av rod 5 which extends downwardly from the upper part thereof into a tube 6. The lower end of the rod 5 is provided with an enlargement 5'. The upper end of the tube 6 carries a cap member 13 having an opening therein for permitting longitudinal movement of the rod 5. The enlargement 5' and the opening in the cap member provides means for guiding axial movements of the rod.

The tube 6 extendsdownwardly from a position within the hollow portion of the floatable 56 valve member and thereafter curves and extends outwardly through the wall of the drain pipe 3 and terminates adjacent the manually operable means indicated generally at C. Thus the hollow shaped floatable valve member covers the upper end of the tube 6 even when the valve is in open 5 position as illustrated in Fig. 2. The lower end of the tube 5 which projects beyond the wall of the drain pipe 3 is provided with a cap member 9 having an opening therein for receiving a bar member 8'. The tube 6 is also partly filled with 10 a plurality of weighted spherical-shaped means or balls H having diameters substantially equal to the inner diameter of the tube. These balls are moved within the tube 6 by means of the bar 8 which may be moved into the lower end of the 15 tube 5 by depressing the tubular-shaped button 8 which surrounds the bar 8'. Thus the balls may be moved upwardly within the tube 6 so as to engage the enlargement 5 and move the valve member upwardly and permit liquid from the 20 tank a to be discharged in the drain pipe. The tubular-shaped button 8 is returned to the inoperative position by means of a spring In which surrounds the bar 8 and engages the cap member 9 and the tubular-shaped button. 2

When the tank a is empty the fioatable valve member b and the rod 5 move downwardly and close the opening to the drain pipe 3. The elastic skirt portion of the floatable valve member engages the conical-shaped opening provided in the bushing 4 to seal the lower end of the tank. Thus when water flows into the tank a through the valve l the valve member remains closed and after the liquid flowing into the tank reaches a predetermined level the valve lis closed by means of the float 2. Such. a position of the parts is illustrated at Fig. 1. I

When it is desired to discharge the liquid from the tank a into the water closet the button 8 is depressed and the bar 8' pushes the balls- H upwardly in the tube 6 to force the valve member 4 upwardly. Water is thus discharged into the drain pipe 3 and the fioatable valve member remains lifted by reason of its buoyancy but the rising of the valve member is limited by means of a stop I2 fixed to the rod 5 and further upward movement of the valve member is prevented when the stop member engages the cap member. 13. Thus the button 8 may be released and the liquid will continue to discharge into the drain 50 pipe until the weight of the valve member and the rod 5 overcome the buoyancy of any small amount of water remaining in the tank I and move to the closed position.

. It is to be no-ted that the manually operable means is positioned below the valve but danger of leakage through the tube 6 is prevented since the floatable valve member acts as a bonnet to cover the upper end of the tube 6 even when the valve member is in an open position as illustrated in Fig. 2.

While the invention has been described with reference to specific structural details it will be appreciated that changes may be made therein. Such modifications may be made Without departing from the spirit and scope of the invention as set forth in the appended claims.

I claim:

1. In a valve mechanism for Water closets having a tank and a drain pipe extending downwardly therefrom, a floatable valve member arranged within the tank to close the drain pipe,

a tube extending downwardly from the valve member and through the pipe wall, a plurality of balls arranged within the tube, each ball having a diameter substantially equal to the inner diameter of the tube, a rod carried by the valve member extending into an end of the tube adjacent the valve member, a manually operable bar extending into the other end of the tube for pushing the balls upwardly whereby an end ball within the tube engages said rod to move said valve member to an open position so as to float in the Water of the tank, and means carried by the rod limiting the upward movement of the valve member.

2. In a valve mechanism for water closets having a tank and a drain pipe extending downwardly therefrom, a hollow valve member arranged within the tank to close the drain pipe, the lower end of said valve member having an opening therein, a tube extending upwardly into said valve member through said opening and terminating within said valve member, a rod carried by the valve member extending into said tube, a plurality of balls arranged within the tube, each ball having a diameter substantially equal to the inner diameter of the tube, the lower end of said tube terminating outside said pipe and below said valve member, and manually operable means associated with the lower end of the tube for pushing said balls upwardly.

3. In a valve mechanism for water closets havly therefrom, a hollow valve member arranged within the tank to close the drain pipe, the lower end of said valve member having an opening therein, a tube extending upwardly through said opening so that the valve member covers the end of said tube, a rod carried by the valve member extending into said tube, and weighted means arranged within said tube adapted to be moved into engagement with said rod for moving said valve member upwardly so as to float in the Water of the tank, and means carried by said rod limiting the upward movement of the valve member.
